CCTV Camera Types many important features, like lens control output, Back Light Compensation and many more. Speco IR-200 Infrared IlluminatorOf course, if you want IR-illumination to work, you have to use the right cameras. Black-and-white surveillance cameras are the most IR-sensitive; most color-cameras are equipped with filters that block out infrared light to enhance image quality. Many manufacturers have come out with IR-sensitive dual-mode cameras, which offer color images and can switch from daytime to night vision automatically, but the IR-sensitivity of these, too, varies according to the camera. So if you're investing in a CCTV system and want to incorporate IR illumination, make sure you check the cameras for IR-sensitivity in advance. based on intended implementation and requirements. Types of IR Illuminators Today, increasing numbers of domestic households adopt CCTV systems as a common means of protection and communication. Spy cameras vary in size and design. Actually, the word disguise, rather than design, is probably a better word for describing spy cameras. Theoretically DVRs can record for weeks on end, depending of course on memory, recording quality and speed. A camera located in a semi-public area such as your front porch can be put in a vandal resistant dome for protection. Monitoring software could always be updated and you can always add more memory space.
There is nothing negative about a house owner or a concerned parent wanting to protect his family and property. This is good for, say, tracking criminals who don't stay in one place, or for catching action that's outside the camera's range.
There are two major types of digital recorders on the market right now. They can easily be relocated without having to rely on nearby power or communication sources. It is great for use in stores, lobbies, gas stations and other public places. Practical solutions for covert installation also include Motion and Smoke Detector cameras, although they are absolutely not a substitute for your security alarm or fire protection. This is good for, say, tracking criminals who don't stay in one place, or for catching action that's outside the camera's range. Exchangeable lenses enable this camera, to monitor objects from virtually any distanceAlthough intended for indoor use, they can be used for outdoors when combined with weatherproof housing. Lenses in these cameras are either of a normal industry aperture or a "pinhole" lens of very small aperture. For example, why use cameras with 500 TV lines of resolution with a monitor that offers only 380 or less. There are three main types of IR illuminators: diodes, lamps, and lasers. Diodes are small, inexpensive, and good for short-range illumination. They also require relatively little power to operate. Infrared lamps are more expensive to buy and maintain, but they can operate at greater distances and are often better for facial identification. Lasers are excellent for long-range image clarity, even in inclement weather, but they're big, expensive, and potentially harmful to the eye if not handled correctly-which is why they're usually only reserved for military use. CCTV systems An IR-illuminator is a device that emits infrared light-low frequency electromagnetic radiation that's outside the visible spectrum. In other words, it gives off light that a camera can pick up and use, but that a person can't see-so while it's still dark to the human eye, the camera can see just fine.
When choosing a camera you'll have to consider two more aspects: the viewable image size and your preference of B/W or color. IR Illuminators and CCTV
